Lightweight 100 mm stroker cranks available exclusively from Buschur Racing
The BR 2.3RPM engines have been working out fantastic. I wanted to take the engines a step further and lighten up the rotating assembly more, without spending a bunch of money.
I called our partners over at Manley and asked about having a crank shaft built specifically for our engine builds. This has been over 6 months in the making and we finally have them available!
A standard 100mm Mitsubishi crankshaft is 35.3 pounds.
The billet 100mm Manley crank we have been using is 33.5 pounds.
The new Manley/BR 100mm billet crank is only 29 pounds!
Here is a picture of this piece of art, enjoy:

I will post pricing as soon as it's set in stone. We will have a dealer program for any shops to buy these from us so they will be available to everyone but only through us.

For sure a lighter rotating assembly revs faster, I can feel it and hear it in the builds we do, especially one with a light weight carbon Tilton clutch, as it's about 20 pounds off the clutch weight. Power is measurable too, as the cars that I've seen make the most power have always had the lightest rotating assembly. Changing the rotating assembly weight in a build to just dyno back-to-back differences is obviously something we haven't done, but it sure would make for an interesting test. It's a lot like raising the compression in the engine. The seat of the pants difference is there, no doubt, measuring it on the dyno though........a different story. As for longevity, that is always a main concern and dropping weight on the crank is one of the places you can drop the most weight.
I don't feel any one of those things are the "BIGGEST" place you will notice the difference but all of them combined.

I figured this might be the case, just didn't know if there was a variable that stood out from the others. Wish I had this crank in my 2.3!!!

I am waiting on final pricing. Pricing is going to be delicious though! I have to get it all worked out because of the dealer offerings which we don't usually do (to any dealer that is). This is exclusive to us. I think pricing is going to be right in line with their current 100 mm billet crank we use.
Yes, this is going to make it's way into the 2.3 RPM engine. Right now I need to get it into a high horsepower 2.3 build for immediate use to make sure all goes well. I am super confident in the product and reliability based on everything else we use from Manley.

OK, I spoke with Tripp today at Manley. He wants this crank in an engine and run hard first. So full release depends on that.
Anyone looking for a 2.3RPM engine? I'll cut a break on ONE with this crank but it has to be a build that is going to go together soon and be run pretty hard. NO half assed tuners, NO half assed builders, I need a professional or someone to bring a car here so we can professionally take care of the build.
Pricing, for retail will be $1578 on these cranks.
